A stable connection sandwich panel

Abstract

A stable sandwich panel includes an inner panel and an outer panel, with a filler material between them. The surfaces of the inner and outer panels are connected by U-shaped connectors. Each U-shaped connector includes a first connecting edge connected to both the inner and outer panels, a supporting edge connected to the first connecting edge, and a second connecting edge connected to the supporting edge. The height of the supporting edge is such that the second connecting edges hook onto each other at the midpoint between the inner and outer panels. Compared to existing technologies, this stable sandwich panel provides U-shaped connectors on both sides and in the middle of the inner and outer panels, connecting them to each other. This results in a stable connection structure and prevents bulging.

Description

Technical Field

[0001] This utility model relates to the field of sandwich panel technology, specifically to a sandwich panel with a stable connection. Background Technology

[0002] Sandwich panels consist of an inner panel, an outer panel, and fillers. During manufacturing, the inner and outer panels are coated with adhesive and then bonded together with the fillers. However, after prolonged use, the adhesive evaporates, causing the adhesive layer to lose its stickiness. This leads to the separation of the inner and outer panels from the fillers, resulting in bulging. Consequently, the strength and thermal insulation performance of the sandwich panel decrease. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sandwich panel with a stable connection, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A stable sandwich panel includes an inner panel and an outer panel, with a filler material disposed between the inner and outer panels. The surfaces of the inner and outer panels are connected by a "U"-shaped connector. The "U"-shaped connector includes a first connecting edge, which is connected to both the inner and outer panels. A support edge is connected to the first connecting edge, and a second connecting edge is connected to the support edge. The height of the support edge is such that the second connecting edges hook onto each other at the midpoint between the inner and outer panels.

[0006] Furthermore, the angle between the second connecting edge and the supporting edge is 88.5°~89°.

[0007] Furthermore, the "U"-shaped connectors are located on both sides and in the middle of the inner and outer plates, respectively.

[0008] Compared with the prior art, the sandwich panel of this utility model with stable connection is provided with "U"-shaped connectors on both sides and the middle of the inner and outer panels. The "U"-shaped connectors are connected to each other, and the connection structure is stable, avoiding the bulging phenomenon. Attached Figure Description

[0012] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0013] like Figure 1 and Figure 2 As shown, a sandwich panel with stable connection includes an inner panel 1 and an outer panel 2. A filler 3 is provided between the inner panel 1 and the outer panel 2. The filler 3 is bonded to the inner panel 1 and the outer panel 2 with adhesive. A "U"-shaped connector 4 is connected to the surface of the inner panel 1 and the outer panel 2. The "U"-shaped connector 4 is formed by bending the sheet material. The "U"-shaped connector 4 includes a first connecting edge 411, a supporting edge 412 connected to the first connecting edge 411, and a second connecting edge 413 connected to the supporting edge 412. The first connecting edge 411 is connected to the inner panel 1 and the outer panel 2 respectively. When installing the "U"-shaped connector, the "U"-shaped connector is positioned by a positioning fixture. The first connecting edge 411 is fixed to the inner panel 1 and the outer panel 2 by spot welding or welding. The height of the supporting edge 412 is just enough to allow the second connecting edge 413 to hook together at the middle position of the inner panel 1 and the outer panel 2.

[0014] In this embodiment, the angle between the second connecting edge 413 and the supporting edge 412 is 89°, with a tolerance of 0 to -0.5°. This ensures a tight connection between the second connecting edges 413 during the hooking process. During the splicing process, due to the use of a negative tolerance bending angle, to facilitate the splicing of the "U"-shaped connectors, the entrance of the second connecting edge 413 on the surface of the inner plate 1 is raised upwards to enlarge the opening at the entrance of the "U"-shaped connector, making it easier for the second connecting edges 413 to hook together. At the same time, in this embodiment, the "U"-shaped connectors 4 are located on both sides and in the middle of the inner plate 1 and the outer plate 2, respectively, to ensure a stable connection between the inner plate 1 and the outer plate 2 and to prevent detachment from the filler.

[0015] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
